Description
Clare and IXYS have combined to bring OptoMOS® technology, reliability and compact size to a new family of High Power Solid State Relays. As part of this new family, the CPC1777 single pole normally open (1-Form-A) DC Solid State Relay employs optically coupled MOSFET technology to provide 2500Vrms of input to output isolation.
The output is constructed with an efficient MOSFET switch and photovoltaic die that uses Clare’s patented OptoMOS architecture while the input GaAlAs infrared LED provides the optically coupled control. The combination of low on-resistance and high load current handling capability makes this relay suitable for a variety of high performance DC switching applications.
The unique i4-PAC package pioneered by IXYS allows solid state relays to achieve the highest load current and power ratings. This package features an IXYS unique process where the silicon chips are soft soldered onto the Direct Copper Bond (DCB) substrate instead of the usual copper leadframe. The DCB ceramic, the same substrate used in high power modules, not only provides 2500Vrms isolation but also very low thermal resistance (0.35°C/W).
